Welcome to the Q&A Forum

I am having some trouble with getting the landing pages for a clients website to show up in the SERPs. 
As far as I can see, the pages are optimized well, and they also get indexed by Google. The website is a danish webshop that sells wine, www.vindanmark.com Take for an instance this landing page, http://www.vindanmark.com/vinhandel/ 
It is optimzied for the keywords "Vinhandel Århus".   Vinhandel means "Winestore" and "Århus" is a danish city. As you can see, I manage to get them at page 1 (#10), but it's the frontpage that ranks for the keyword. And this goes for alle the other landing pages as well. But I can't figure out, why the frontpage keep outranking the landingpages on every keyword. 
What am I doing wrong here?
